DETAILED DESCRIPTION

While this technology is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the technology and is not intended to limit the technology to the embodiments illustrated.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present technology. As used herein, the singular forms “a”, an and the are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It is noted at the outset that the terms “coupled,” “connected”, “connecting,” “electrically connected,” etc., are used interchangeably herein to generally refer to the condition of being electrically/electronically connected. Similarly, a first entity is considered to be in “communication” with a second entity (or entities) when the first entity electrically sends and/or receives (whether through wireline or wireless means) information signals (whether containing data information or non-data/control information) to the second entity regardless of the type (analog or digital) of those signals. It is further noted that various figures (including component diagrams) shown and discussed herein are for illustrative purpose only, and are not drawn to scale.

It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings with like reference characters. It will be further understood that several of the figures are merely schematic representations of the present technology. As such, some of the components may have been distorted from their actual scale for pictorial clarity.

Turning now to FIG. 1, an example security system 10 is illustrated. The security system 10 generally comprises a mobile device 15, a computing device 20, a security device 25, and an environment 30 that includes at least one object 35. It will be understood that in some instances, the security system 10 may include other combinations of components such as computing device 20 and security device 25, such that the mobile device 15 is not present. Also, in some embodiments, the security device 25 can be embedded or integrated into the computing device 20 or into a protective cover (see FIG. 3) for the computing device 20.

The environment 30 includes any location at which the computing device 20 is positioned. For example, the computing device 20 is located in a coffee shop, a library, or other location. Located within the environment are objects, such as the at least one object 35. The objects in the environment include, for example, tables, chairs, walls, ceilings, individuals, and so forth. These objects are located proximal or distant from the computing device 20. In some embodiments, the sensor(s) used in some embodiments of the security device 25 use motion sensing features that employ ultrasonic or Doppler wave measurements which reflect sound or microwave signals off of the objects within the environment 30 as a means to determine the movement of the computing device 20. Additional details regarding these movement detection methods will be provided infra.

Broadly, the security device 25 is configured to sense movement of the computing device 20 and output a warning to the computing device's owner that the computing device 20 has moved. In some instances, the security device 25 can sense the gyration of the computing device 20 rather than a more deliberate movement such as picking up or carrying of the computing device 20. Warnings can be tailored or scaled to whether the computing device 20 has been moved or gyrated. The word gyrated will be understood to include bumping, oscillating, tapping, or other small movements of the computing device 20. The security device 25 is configured to output different types or combinations of warning messages depending upon whether the computing device 20 has been gyrated or moved. Again, additional details regarding these specific features are provided in greater detail below.

In other embodiments, the sensors used with the security device 25 can determine movement of individuals proximate the computing device 20. For example, the passive infrared (IR) and other heat sensors can be used to determine if individuals are proximate the computing device 20. Using the sensor message generated by these types of sensors, the security device 25 can output various warning messages. The user can set the sensitivity level of the security device 25. For example, the user can specify that the sensor should detect a consistent heat signature proximate the computing device 20 for at least thirty seconds before outputting a warning message.

The mobile device 15 may pair/couple with the security device 25 using any wired or wireless methodologies. Generally, the wireless methods will form a network or communications path (hereinafter “network 40”). An example of a network may include a telecommunications network, a Bluetooth pairing, infrared (IR), near field communications (NFC), or other similar methods for communicatively linking the security device 25 with the mobile device 15.

The network 40 may include any one of a number of private and public communications mediums such as the Internet. Other suitable networks may include or interface with any one or more of, for instance, a local intranet, a PAN (Personal Area Network), a LAN (Local Area Network), a WAN (Wide Area Network), a MAN (Metropolitan Area Network), a virtual private network (VPN), a storage area network (SAN), a frame relay connection, an Advanced Intelligent Network (AIN) connection, a synchronous optical network (SONET) connection, a digital T1, T3, E1 or E3 line, Digital Data Service (DDS) connection, DSL (Digital Subscriber Line) connection, an Ethernet connection, an ISDN (Integrated Services Digital Network) line, a dial-up port such as a V.90, V.34 or V.34bis analog modem connection, a cable modem, an ATM (Asynchronous Transfer Mode) connection, or an FDDI (Fiber Distributed Data Interface) or CDDI (Copper Distributed Data Interface) connection. Furthermore, communications may also include links to any of a variety of wireless networks, including WAP (Wireless Application Protocol), GPRS (General Packet Radio Service), GSM (Global System for Mobile Communication), CDMA (Code Division Multiple Access) or TDMA (Time Division Multiple Access), cellular phone networks, GPS (Global Positioning System), CDPD (cellular digital packet data), RIM (Research in Motion, Limited) duplex paging network, Bluetooth radio, or an IEEE 802.11-based radio frequency network. The network 40 can further include or interface with any one or more of an RS-232 serial connection, an IEEE-1394 (FireWire) connection, a Fiber Channel connection, an IrDA (infrared) port, a SCSI (Small Computer Systems Interface) connection, a USB (Universal Serial Bus) connection or other wired or wireless, digital or analog interface or connection, mesh or Digi® networking.

The mobile device 15 may comprise an application that controls the arming and disarming of the security device 25, and the application can display warning messages received from the security device 25. The application is stored in memory and executed by the processor of the mobile device 15. Suitable examples of a processor and memory are found with respect to the computing device or machine of FIG. 16.

FIGS. 2-13 individually and collectively illustrate example security devices that can be utilized in accordance with the present technology. Some descriptions of operational features of security devices illustrated in FIGS. 2-13 may refer back to components described in FIG. 1 for purposes of context and operating environment.

FIG. 2 is a schematic diagram of an example security device 200, constructed in accordance with the present technology. The security device 200 generally comprises a computing interface 205, a power converter 210, a processor or CPU 215, a transmitter 220, an audio device 225, and motion sensor 230, and an object 35 (see FIG. 1) that is included in an environment in which the security device 200 is positioned.

The components of the security device 200 outlined above can be coupled or fabricated onto a substrate 205A. The substrate 205A is, in some embodiments, integrated into a motherboard of a computing device. In another example, the substrate 205A is a standalone substrate that can be stored with a housing. Other embodiments described herein illustrate a security device that is positioned within a housing or enclosure.

The computing interface 205 can include any physical interface that would allow the security device 200 to communicatively and/or electrically couple with the computing device. For example, the computing interface 205 may include a serial port connector, a USB port connector, a FireWire connector, a headphone jack, or any other physical connection type that would be known to one of ordinary skill in the art with the present disclosure before them.

The power converter 210 is an optional component that is used when the security device 200 draws power from an external power source such as the battery of a computing device. The power converter 210 can modify input power received from the computing device, either stepping the input power down or amplifying the input power to meet the needs of the components of the security device 200. In some embodiments, the security device 200 comprises an integrated power source such as a battery (not shown).

The processor 215 is configured to store various algorithms that are used to detect the movement or gyration of the computing device 20 (see FIG. 1). The types of algorithms used to detect movement or gyration depend upon the type of motion sensor(s) that are included in the security device 200. Use case examples of certain combinations of sensors and thresholds will be described in greater detail below.

The motion sensor 230 may include a single sensor or a plurality of sensors. The plurality of sensors can include a plurality of the same type of sensors or many different combinations and permutations of motion sensors. Examples of motion sensors include, but are not limited to, accelerometers, passive infrared sensors that detect body heat from individuals, ultrasonic sensors that sense the movement of the sensors relative to other objects adjacent to the sensors, microwave sensors, and tomographic sensors or network of tomographic sensors, as well as combinations thereof—just to name a few. Other suitable motion sensors may also likewise be utilized in accordance with the present technology.

FIG. 3 is a perspective view of another example security device 300 that is integrated into a protective cover 305 for a computing device. The components of the security device 300 can be embedded into the protective cover 305 or the components can be attached to an outer surface of the protective cover 305 in a recess 335 formed into the protective cover 305. As with the security device 200 of FIG. 2, the security device 300 of FIG. 3 comprises a motion sensor or sensors 310, an audio device 315 such as a speaker, a processor or CPU 320, a transmitter 325, and an interface 330 for coupling with a computing device.

FIG. 4 is a perspective view of another example security device 400 where the components are in a stacked configuration. More specifically, the security device 400 comprises a transmitter 405 that is transverse and above an audio device 410. The audio device 410 is transverse and above a motion sensor 415. The motion sensor 415 is transverse and above a power unit 420. The security device 400 includes a physical interface 425, such as a USB interface that extends from the power unit 420. The device also comprises a processor or CPU that is enclosed in a housing 450 that houses all of the components except the interface 425.

FIG. 5 illustrates an example security device 500 that comprises a USB connector 505. FIG. 6 illustrates an example security device 600 that comprises a serial port connector 605. FIG. 7 illustrates an example security device 700 that has a pin connector 705. FIG. 8 illustrates an example security device 800 that includes a locking connector 805. The locking connector 805 is configured to be difficult to remove when the locking connector 805 mates with a physical interface of the computing device. For example, the locking connector 805 may have a shape with a large upper section and a relatively smaller lower section, forming a trapezoid. The larger upper section is sized such that the locking connector 805 is difficult but not impossible to remove from a computer interface. For example, a trapezoidal shape of the locking connector 805 will ensure that the locking connector 805 is removable in a directional manner. In one embodiment, the trapezoidal shape of the locking connector 805 ensures that the locking connector 805 can only be removed by pulling along a linear axis of the locking connector 805, where the linear axis extends along a centerline that runs through a center point of the locking connector 805 (the center point would be in the center of the face illustrated in FIG. 8).

FIG. 9 is another example connector 900 that can couple a security device 905 with a computing device. The connector 900 comprises a clamp that has an upper bracket 915 and a lower bracket 920 that are spaced apart to form a groove 925. The groove 925 receives a portion of a computer, such as a chassis or screen. A locking knob 930 can be turned to move the upper bracket 915 and lower bracket 920 towards one another to decrease the size of the groove and aid the connector 900 in clamping around an object. The connector 900 can also comprise resilient teeth 935 that can also exert forces on the portion of the computing device held within the groove 925. The teeth 935 can be formed from a plastic, a rubber, or any other resilient material.

FIG. 10 is another example security device 1000. The security device 1000 generally comprises an interface 1005, a housing 1010, a flexible connector 1015, and a motion sensor 1020. While not shown, the security device 1000 includes, in some embodiments, a CPU, a power unit, a transmitter, and other components described in the various other embodiments.

The flexible connector 1015 allows the motion sensor 1020 to be flexibly positioned in any direction 360 degrees relative to the security device 1000, as well as any object 35 (see FIG. 1) in the general area of the security device 1000. For example, the object 35 may include a table on which a computing device is positioned. The motion sensor 1020 is positioned to point downwardly to face the object 35. Because the motion sensor 1020 can be either an ultrasonic sensor or a microwave sensor that each use waves to detect distances, the motion sensor 1020 of the security device 1000 can determine when the sensed distance changes, indicating that the computing device has been moved. If the sensor comprises a passive IR device or a tomographic sensor, the flexible connector 1015 can be positioned so that the sensor is in a position that is optimal for the sensor to detect movement. For example, if the sensor is a passive IR sensor, the sensor could be positioned to point at a position directly in front of the display of the computing device to detect heat signatures in front of the computer. The flexible connector 1015 may be referred to as a means for positioning a sensor.

FIG. 11 illustrates another example security device 1100 that also comprises a flexible connector 1105. The security device 1100 also comprises an interface 1110 for coupling the device with a computing device, as well as an audio device 1115, a housing 1120 that encloses a CPU (not shown but referenced in other figures such as FIG. 2). The security device 1100 also comprises a transmitter 1125. The transmitter 1125 can be housed in a column enclosure 1130 that extends from the housing 1120.

The flexible connector 1105 extends from the column enclosure 1130 and a sensor 1135 for the security device 1100 is connected to a terminal end of the flexible connector 1105. In this embodiment, the flexible connector 1105 can include a flexibly positionable cable or wire that allows the sensor 1135 to be directed in any position 360 degrees relative to the security device 1100. FIG. 11 illustrates the sensor 1135 in various positions. Again, the positioning of the sensor 1135 depends on the sensor used in the security device 1100.

FIG. 12 illustrates another embodiment of a security device 1200. The security device is constructed with components similar to those of FIGS. 2-11. The security device 1200 includes a set of sensors 1205A-F that are positioned on a platform 1210 that extends normally to a housing 1215 that houses the components of the security device 1200 such as a transmitter and CPU.

The platform 1210 has a first sensor 1205A positioned on a top of the platform 1210, a second sensor 1205B positioned on a bottom of the platform 1210, and third and fourth sensors 1205C and 1205D which are positioned on opposing sides of the platform 1210. A fifth sensor 1205E is located on the platform 1210 on an outward side of the platform 1210. A sensor 1205F is located on the platform 1210 on a side of the platform 1210 that extends from an opposing side of the housing 1215. That is, part of the platform is positioned on one side of the housing 1215, while another part of the platform 1210 is positioned on an opposing side of the housing 1215. It will be understood that fewer or more sensors can be used.

In this example, the security device includes a plurality of sensors because each of the sensors 1205A-F is capable of sensing only in a directional manner. Thus, to cover a wider area, many sensors are used. In some embodiments, the plurality of sensors 1205A-F are identical sensors. In other embodiments, the plurality of sensors 1205A-F include different types of sensors. For example, the plurality of sensors include one accelerometer, two or more ultrasonic sensors, and at least one passive IR sensor.

FIG. 13 illustrates an example security device 1300 that is embedded into a chassis 1305 of a computing device. For example, the chassis 1305 may include a bottom portion of a frame or case of a computing device.

FIG. 14A is a flowchart of an exemplary method for securing a computing device based on movement of the security device. The method can be executed by one or more of the security devices described herein. The method includes receiving from the sensor messages indicative of the movement of the computing device 1405. For example, if the sensor is an accelerometer, the accelerometer can determine movement of the computing device by detecting changes in acceleration of the accelerometer.

In another example, movement of the security device can be sensed using an ultrasonic sensor or other similar sensor that measures distances between the sensor and adjacent objects. When the distance between the sensor and the adjacent objects changes, the CPU of the security device can determine that the security device has moved, and therefore the computing device to which the security device is connected.

The method can further include determining if the computing device has been moved 1410. Again, the CPU calculates this determination by executing instructions that allow the CPU to process sensor messages indicative of the movement of the computing device. Again, the exact methods used by the CPU will depend on the type of sensor used. For example, the CPU can measure changes in acceleration if the sensor is an accelerometer. If the sensor is an ultrasonic sensor, the CPU can be configured to measure changes in distance as detected by the sensor.

If no movement is detected, the CPU can take no action. If movement of the security device is detected, the method includes outputting a warning message using a transmitter if the computing device has been moved 1415.

FIG. 14B is a flowchart of an exemplary method for securing a computing device based on presence and proximity of individuals to the security device. The method can be executed by one or more of the security devices described herein such as a passive IR or heat sensor. The method includes receiving from the sensor messages indicative of the movement or proximity of individuals near or proximate the computing device 1420. For example, if the sensor is a passive IR sensor, the passive IR sensor can sense heat signatures from individuals who are near the computer.

The method can further include determining if one or more individuals are proximate the computing device 1425. Again, the CPU calculates this determination by executing instructions that allow the CPU to process sensor messages indicative of individuals that are proximate the computing device. Again, the exact methods used by the CPU will depend on the type of sensor used. For example, the CPU can measure changes in heat signatures or patterns measured by the passive IR sensor. The CPU can establish thresholds for heat signatures, above which it is assumed that someone is in close proximity to the security device or computing device. Lower heat signature values indicate that individuals may be passing by the device but not close enough to require a warning.

If no individuals are proximate, the CPU can take no action. If individuals are determined to be proximate the security device, the method includes outputting a warning message using a transmitter if the computing device has been moved 1430.

In some instances, the methods of FIGS. 14A and 14B are executed concurrently such that the security can determine both movement/gyration of the computing device, as well as the presence or proximity of individuals to the computing device. In these instances, it will be understood that the security device would comprise at least two types of sensors, one for sensing the movement/gyration of the device and a second for sensing the presence or proximity of individuals to the computing device.

FIG. 15 is a flowchart of an exemplary method for selectively outputting warning messages in accordance with detected movement or gyration. It is assumed for this example that the sensor is an accelerometer and that the security device is coupled to a computing device. The CPU can use established rules that are stored in memory and allow the CPU to evaluate if the security device has been moved or merely gyrated (e.g., bumped).

The method includes receiving from the sensor messages indicative of the movement of the security device 1505. To be sure, because the security device is coupled with the computing device, it is assumed that movement of the security device is also indicative of movement of the computing device.

The method includes evaluating the sensor messages to determine if the computing device has been gyrated rather than moved 1510. For example, the CPU can compare sensor messages from the accelerometer to a rule that specifies that if the acceleration is short lived (for example, a second or two), that the security device has been gyrated or bumped rather than moved. If the acceleration is long lived (for example, ten seconds or more or continuous), the security device should be considered by the CPU as having been moved.

Different warning messages can be output based on whether the CPU detects gyration or movement. For example, the CPU will output a short audio warning tone if gyration is detected. On the other hand, the CPU will output a warning message for display on either the computing device or the mobile device and a long audio warning tone if the security device detects movement.

Thus, the method includes causing either an audio device to output a warning signal that the computing device has been gyrated or the transmitter to output a signal that is indicative that the computing device has been gyrated 1515.

In some embodiments, the security device is paired with a mobile device over a communications path. Thus, the method may include outputting the warning messages by a transmitter of the security device to the mobile device over the communications path.

Returning back to FIG. 1, in an example use of a security device and system, an end user of the computing device 20 desires to walk away from the computing device 20. The end user secures the computing device 20 by inserting the security device 25 into a physical port of the computing device 20. Again, the exact physical port chosen will depend upon the interface included on the security device 25. In this example, it is assumed that the security device 25 includes a USB connector and the USB connector is inserted into a USB port of the computing device 20.

In some instances, when the security device 25 is coupled with the computing device 20, the security device 25 automatically arms and begins sensing either: (1) the motion of the computing device; or (2) the presence or motion of individuals proximate the computing device 20. The word “proximate” will be understood to be a relative term that depends upon the capabilities of the sensing device used in the security device 25. For example, one type of sensor may be capable of sensing the presence of individuals who are one to three feet away from the computing device 20, while another type of sensor may be capable of sensing individuals who are up to five feet away from the computing device 20. The proximity of an individual to the computing device 20 is a distance of the individual from the computing device 20. The proximity of the individual can also refer to the presence of the individual in front or near the computing device 20. Thus, an individual is “proximate” the computing device 20 if the individual is sitting in front of the computing device 20 or holding the computing device 20, in two examples.

Assuming the sensor included in the security device 25 includes an accelerometer, the CPU of the security device 25 will begin receiving signals from the accelerometer and determining if the computing device 20 has moved or has been gyrated. In the example, while the end user of the computing device 20 is away, a second individual picks up the computing device 20 and moves the computing device 20. The accelerometer outputs signals that are interpreted by the CPU as movement. The CPU outputs a warning message such as activating the audio device (e.g., speaker) of the security device 25 to output a warning tone, alerting those around that the computing device 20 has been moved.

In a second use case example, it will be understood that the security device 25 is coupled with the mobile device 15. When the security device 25 is inserted into the computing device 20 it is in an unarmed state, meaning that it is not sensing movement. The security device 25 pairs with the mobile device 15. The mobile device 15 can transmit to the security device 25 an arming signal that causes the security device 25 to determine movement.

When the security device 25 senses movement of the security device 25/computing device 20, the security device 25 not only outputs a warning message that includes activating the speaker to output a warning tone, but the security device 25 transmits a warning message to the mobile device 15 over the network 40. In one example, the mobile device 15 can display a message that the security device 25/computing device 20 have moved. In another example, the mobile device 15 can display a message that the security device 25/computing device 20 have moved and may also output a warning tone using the speaker of the mobile device 15. The warning tone alerts the end user of the mobile device 15 and can display a message that the security device 25/computing device 20 have moved.

FIG. 16 is a diagrammatic representation of an example machine in the form of a computer system 1600, within which a set of instructions for causing the machine to perform any one or more of the methodologies discussed herein may be executed. In various example embodiments, the machine operates as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine may be a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a cellular telephone, a portable music player (e.g., a portable hard drive audio device such as an Moving Picture Experts Group Audio Layer 3 (MP3) player), a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.

The example computer system 1600 includes a processor or multiple processors 1605 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), or both), and a main memory 1610 and static memory 1615, which communicate with each other via a bus 1620.

FIG. 17 is a schematic view of an exemplary security system 1700 having a security device 1720 that is coupled to a computing device 1710. In various embodiments, the security system 1700 comprises a computing device 1710, a security device 1720 with one or more sensors 1730, a transmitter 1740, a network 1750, a server 1760, and a mobile device 1770 with an application 1780. It will be understood that, in some instances, the security system 1700 may include other combinations of components (including more or fewer components, such as computing device 1710 and security device 1720, such that mobile device 1770 is not present). Also, in some embodiments, the security device 1720 can be embedded or integrated into the computing device 1710 or into a protective cover (for example, see FIG. 3) for the computing device 1710. In other embodiments, the security device 1720 is coupled to the exterior of the computing device 1710 or plugged into the computing device 1710 (for example, similar to a USB flash drive).

The mobile device 1770 may pair/couple with the security device 1720 using any wired or wireless methodologies. Generally, the wireless methods will form a network or communications path (hereinafter “network 1750”). The wireless connection methods may include Wireless Fidelity (Wi-Fi), Super Wi-Fi, Light Fidelity (Li-Fi), Free-space optical (FSO) communication, laser transmission, cellular phone signal and data signal, and electromagnetic spectrum technology. Furthermore, the wireless methods may include any of those described above in regards to mobile device 15, security device 25, and network 40 of FIG. 1. The network 1750 may include any one of a number of private and public communications mediums such as the Internet. Other suitable networks may include or interface with any one or more of those described in detail above in regards to network 40 of FIG. 1.

The mobile device 1770 may comprise an application 1780 that controls the arming and disarming of the security device 1720, and the application 1780 can, for example, display warning messages or emit an audio warning signal when the computing device 1710 has been moved. The application 1780 is stored in memory and executed by the processor of the mobile device 1770. Suitable examples of a processor and memory are found with respect to the computing device or machine of FIG. 16, as previously described in detail.

FIG. 18 is a flowchart of an exemplary method 1800 for determining movement of a computing device based on the strength of signals received by a security device coupled to the computing device. The method 1800 can be executed by one or more of the security devices described herein. The method 1800 may include receiving messages pertaining to periodic signals from a mobile device received by one or more sensors of a security device 1810. In various embodiments, the mobile device can include a clock feature that transmits signals periodically to the security device (or “pings” the security device). The signals may be received by the one or more sensors of the security device over a predetermined time increment, for example, every half a second or every one second. The time increment at which the signals or pings are transmitted can be adjusted by a user.

The mobile device can be paired with the security device over a communications path or a network. In various embodiments, the security device may be removably coupled to the computing device. For example, the security device may be embedded or integrated into the computing device. In other examples, the security device may be plugged into a USB port of the computing device. Furthermore, the security device can include a rechargeable battery (including, but not limited to, lithium-ion, nickel cadmium, nickel metal hydride, and lead acid batteries), which may be charged, for example, when plugged into a USB port, via an electrical wall outlet, via an external battery pack, or any other standard methods for recharging a battery. The security device may use non-rechargeable batteries such as alkaline cells, lithium cells, carbon-zinc cells, silver-oxide cells, zinc air cells, and the like.

The method 1800 can further include evaluating the messages to determine if the computing device has been moved 1820. The evaluation of whether the computing device has been moved may include evaluating the strength of the signals received by the one or more sensors of the security device. For example, if the computing device to which the security device is coupled has been moved, the strength of the signals received (for example, the strength of the cellular signals received from the mobile device which can be measured in dBM or other suitable measurements) may fluctuate accordingly. In one embodiment, if the strength of the signals has decreased, this could indicate that the distance between the computing device and the mobile device has increased. In another embodiment, if the strength of the signals has increased, this could indicate that the distance between the computing device and the mobile device has decreased.

In addition to the strength of the signals from the mobile device, other possible detections (or changes that could be measured) could include packet loss, latency issues, physical connection problems, Internet data uploading and downloading speeds (which can be measured in Mbps), and the like, could also indicate that the computing device has been moved.

The messages indicative of movement of the computing device (strength of signal received, packet loss, latency issues, physical connection problems, Internet data uploading and downloading speeds, etc.) may then be sent to a server. At the server, an evaluation can be made as to whether the computing device has been moved (which could indicate that the computing device is being taken by an unauthorized user) or whether the computing device has merely been gyrated.

In various embodiments, an evaluation may be made as to whether the message indicative movement of the computing device is the result of the user of the mobile device moving farther away from the computing device and not the computing device being moved (for example, by an unauthorized user). Other sensors on the security device may include at least one or more motion and/or orientation (inertial) sensors include, for example, magnetometers, accelerometers, gyroscopes, and the like. A magnetometer, such as a compass, measures the strength and/or direction of a magnetic field in order to determine a direction in a frame of reference (e.g., north, south, east, and west). Accelerometers measure acceleration along one or more axes, where the axes are, for example, mutually perpendicular to each other. Gyroscopes (e.g., micro-electro-mechanical systems (MEMS) gyroscopes) measure rotational movement. Additional sensor messages from one or more of these exemplary motion and orientation sensors could further be used in combination with the messages indicative of movement of the computing device to determine if the movement of the computing device is the result of the user of the mobile device moving farther away from the computing device, the result of the computing device being moved by an unauthorized user, the result of the computing device being gyrated, and the like.

In one embodiment, the messages can be evaluated by the security device to determine if the computing device has been moved. In another embodiment, the messages can be evaluated on the computing device to determine if the computing device has been moved. In yet another embodiment, the messages can be sent to a server where the messages are evaluated to determine if the computing device has been moved. The server can be, but is not limited to, an application server (e.g., a software framework that provides both facilities to create web applications and a server environment to run them), which may be a client-server model, request-response model, server-class hardware, and the like. In still another embodiment, the messages can be sent to the mobile device where the messages are evaluated to determine if the computing device has been moved. The messages may be evaluated on the mobile device via an application.

The method 1800 may then include causing the mobile device to output a warning message that the computing device has been moved, if the strength of the signals received is below a predetermined threshold 1830. The predetermined threshold may be determined and adjusted by the user, according to some embodiments. In various embodiments, the warning message is outputted, based on the evaluation of the messages, to indicate that the computing device has been moved by an unauthorized user, and not, for example, if the computing device was merely gyrated or the user has moved farther away from the computing device. In further embodiments, the warning message may include one or more of an audible warning, a visual warning, a textual warning, or any combinations thereof.

FIG. 19 is a flowchart of another exemplary method 1900 for determining movement of a computing device based on the strength of signals received by a security device coupled to the computing device. The method 1900 can be executed by one or more of the security devices described herein. The method 1900 may include receiving messages pertaining to periodic signals from a mobile device received by one or more sensors of a security device 1910. Further examples and descriptions are described in detail with regards to step 1810 of FIG. 18. The method 1900 can further include evaluating the messages to determine if the computing device has been moved 1920. Further examples and descriptions are described in detail with regards to step 1820 of FIG. 18.

The method 1900 may then include causing the security device to output a warning message that the computing device has been moved, if the strength of the signals received is below a predetermined threshold 1930. In some embodiments, the security device can include an audio output device to output the warning message. The warning message may be outputted as a warning tone/sound, spoken word(s), and the like. In other embodiments, the security device can cause the computing device to output the warning message, for example, if the strength of the signals received is below the predetermined threshold. The warning message may be an audible warning, a visual warning, a textual warning, or any combinations thereof, according to various embodiments.

It will be understood that the exemplary security systems described herein may perform one or more methods described above in detail. For example, one exemplary security system may perform both methods 1800 and 1900. In another example, another exemplary security system may perform some but not all of the steps described in methods 1800 and 1900. It will further be understood that the exemplary security systems may perform or include various combinations of any or all of the embodiments described herein.
